Abstract
PURPOSE:To secure correction of the pincushion distortion concurrently to the horizontal deflection by supplying the voltage featuring the horizontal period and the front wire phase-modulated to the switching element and then giving the phase control to turn on the switching element. CONSTITUTION:Capacitor 9 is connected between the connecting middle point of capacitor 5 and coil 6 and that of two diodes. And then the pulse of the horizontal period is supplied 21 to switching transistor Tr2, and then the horizontal deflecting current is flown. Then the voltage featuring the horizontal period with the front wire phase-modulated is supplied to Tr2, and the phase control is given to turn on Tr10. Thus, the pincushion distortion can be given concurrently to the horizontal deflection.
